No. 915,412. Specification of Application filed June 23,

which it appertains to make and use the same. L

This invention relates to incubator devices of the class described wherein an imitation of a brooding hen is employed, and has for one of its'objects to simplify and improve the construction and increase the efiiciency and utility of devices of' this character.

Another object of the invention is to pro- Letters Patent. Patented March 16, 1909. 190a. Serial No. 439,966. 1

illustrating the manner of applying the nonconductive covering to the heating shell.

The improved apparatus comprises a supporting frame having spaced vertical members 1()11 and supporting base structure spectively with spaced transverse apertures 1314 to provide 'means for detachably sup- PATENT oFFIoE.

l 12. The members 10-11 are provided re- I porting the egg receptacles and warming devlces as hereafter explained.

rectangular receptacles 15 preferably of sod, sand, or the like, as indicated at16, upon which'the eggs indicated at 17, rest. Any required number of the rece tacles 15 may be employed, according to t e lengths .of the framework members 1011, but for vide a simply constructed device comprisingq tlie purpose of illustration three of the rean egg" sup orting receptacle and an artificially broo ing element and imparting thereto the necessary warmth to produce the incu bation and likewise to provide means for the care of the chicks after hatching.

Another object of the invention is to provide a simply constructed device wherein the egg supporting portion and the brooding portions may be adjusted andlikewise wherein means are provided for the ins ection and care of the eggs during the hate ing period.

With these and other objectsin view the invention consists in one or more receptacles for the eggs adjustably supported, a covering for the eggs and 'adaptedto be artificially heated and so arranged that the eggs niabe inspected and cared for without disturb ing the heating appliances.

The invention further consists in a supporting framework carrying a plurality of supporting receptacles, a corresponding the egg and warming appliances a apted to be ad- .justed upon the frame.

The invention further consists in certain novel features of construction as hereafter shown and described and then specifically of the im roved apparatus.

pointed out in the claims, and in the drawings illustrating the preferred embodiment of the invention. a

Figure 1 is a side elevation partly in section Fig. 2 is a front view of t e same. Fi 3 is a top lan view. Fig. 4 is a sectional cfetail view ilustrating modification in the construction, and also plained.

The warming element comprises an oblong shell or hollow casing 21 concaved on the under surface, the casings being preferably conper, and are lined within then hollow under surfaces with layers of cotton, wool, 01' the like represented at 30, while the casings are likewise covered upon the outer faces with a suitable non-conducting fabric represented at 33. The cotton lining: may likewise be further increased in thickness with feathers sewing or other means or by suitable cement which will not readily yield to the influence of heat.

The casings 21 are of less length than the receptacles 15 so that spaces are left in the receptacles at the ends for the gatherm 'of the young chicks after hatching,as herea ter explained. The casings 21 will conform to some extent to the natural lien, and the coin caved under side will likewise be formed to represent as far as possible the conditions The egg supporting elements comprise wood and. having deposited therein earth,

to be inspected or cared for, as hereafter eX-.

structed from suitable metal, referably cop as at 34 attached in any suitable manner by heating medium,

present in the body of the natural hen, as to the feathers and other protecting elements. The casings 21 are des1%1ed toreceive the refers. ly hot water, and each w1ll be provi ed with an intake pipe 22 at one end and .a draw off valve 23 at the other end, the pipes 22 ada ted to receive the supply of hot. water an .the valves *23 providing for a constant flow through the casings to thus secure thenecessary continuous uniform heat, as hereafter more fully explained. The casings 21 are formed with ears 24 through which the bolts 20 ass, the same bolts20 y which the receptac es 15 are sus endedbeing thus utilized to suspend the holibw casings, and by providing t e members -1011 with the spaced apertures 13-14 each pair of the rece tacles and the casings may be adjusted relat1ve to each other to any required extent within the range of the s aced apertures, as Wlll be obvious. By

" t means the space occupied by the receptacles and casings may be controlled, as required. 1

- Any required means may be employed for heating the water which is conducted into the casings 21 and as the hot water generator formsno part of the present invention it is not deemed necessary to illustrate it. The hot Water is suppliedthrough a pi e 25 from any suitable source of supply an is fed by branch pi es 26 to the varlous receptacles 21 the branches each provided with arcontrolling valve 27 while the main pipe'25 is likewise provided with controlling valves 28, so

that the receptacles may be independently su plied with the heating medium, or any in lvidual receptacle cut off without interfering with the others if required.

The pipe 25 and itsbranches may be su ported in suitable manner, and for t e purpose of ustration the pipe 25 is shown erected near a wall 29 from WhlCh brackets 30 extend to su port the piping, but it is to be understood t at it is not deslred to limit the invention to any means for arrangin or sup porting hot supply pipes, as they w' 1 be varied as require to a apt the deviceto the locality where it is erected.

If it is desired to inspect the eggs or to care .for them during the hatchin process, the

receptacles 15 may be tilted s ightly by employing a limited degree of force toswing 1 "dium, and means for pivotally The improved device is simple in construct1on, can be extended to any re uired extent by increasing the sizes of t e frames 1011 and supplying an additional number of the receptacles 15.and casings 21 flS'Wlll be obvious. The receptacles 21 are revided with shields 31 of chicken wire to i be detachably connected to the up er edges of the receptacles 15 by inserting t eir ends as at 35in the same to prevent the esca e of the chicks or to revent them from fa lin from the receptac es. These shields 31 be readily detachable so that they can be supplied as soon as the chicks are hatched and will not necessarily be arranged upon the receptacles at an earlier date. The casings 21 will be of metal, as light as ossible consistent with the strains to which they will be subjected, the thinness of the metal increasing the radiating action of the heating medium.

If re uired the drawoff valves 23 will be replace by return pi F1g. 4, and a contro g valve 37 arranged therein, but this will not be a material departure from the invention, as the same results would be obtained, namely to secure the necessary circulation of hot water throughout the casings 21 and thus maintain the tem erature at the required degree.

What is c aimed, is

' 1. In an incubating apparatus, a receptacle for the eg s, a heat imparting element located above e receptacle and comprising. ahollow casing having a concave under surface and adapted to receive the heating mesupporting. the receptacle whereby it may be t' ted independently. of the heat imparting element.

2. In an incubating apparatus, a supporting frame, a plurality of egg receptacles upon said frame, a heating element for each rep ceptacle and located above the same and compmsmg'a hollow casin having a concave under surface 'andv of less ength than the receptacle, and means for pivotally sup orting the receptacle wherebylt maybe t1 ted independently of the heat imparting element.

3. In an incubating apparatus, a receptacle for the-eggs, a heat impartingelement located above the receptacle and com rising a hollow casing having aconcave un er 'sur face and ada ted to receive the heating medium and of ess length than the receptacle, whereby areas-for the chicks areprovided beyond the casing, and meansfor pivotally supporting the recelptacle whereby it may be tilted independent y of the heat imparting element.
